I have a function on a 2d grid that looks like a skewed mound. I

would like to make a contour plot where each contour represents each

sigma, or confidence interval.

I.e. Is there a straight forward way to make such a contour plot where

it is then easy to say: This line is 1-sigma or 68% confidence

interval, this line is 95% confidence interval, etc...

Such plots look like this:

where the first region of each graph is the on sigma or 68%

confidence interval and the second line is the 95% confidence

interval.

Thanks.
